Leak under front grill

[dfwcantor]

Picture attached: 2002 Marathon XLV1S. Can you tell me what this leak is most likely to be? It showed up after a 1100 mile trip, no alarms, noises, problems, etc. It is located on the drivers side just behind the front grill. There is a undercarriage panel with a slot in it which is where it seems to be coming from, but I cannot see the source. It is slightly oily but odorless and colorless.

Any help appreciated, thanks.

On a Country Coach, it would be the AC drain for the dash AC

It's either coolant coming from dash or Webasto heat or power steering fluid. My bet is coolant. My 99 does the same and is dripping ever so slowly from a check valve (I think that is what it is).

Oderless and colorless and leaves a oily spot. I say Freon. Dash condensate tube is over by the door coolant and power steering fluid has smell and color.

Curisair A/C condensate is coming off the evaporators not the condensors

What did U see with the bumper down??

[Joe Camper]

Is there possibly a junair air compressor in there?

How do I lower the bumper? 'Scuse my ignorance.

[Joe Camper]

No dumb questions here. Unless Marathon added another latch or changed what is from Prevo top center of the bumper reach in and over and squeese.

Thanks Joe - dropped the bumper. There is a suspicious looking short rubber hose which is part of the dash air conditioning - I think it is going to turn out to be Freon. Too cold to run it tonight. I'll try running the dash air for a while when we a get a warm day, but I think I have the answer. Thanks to everyone for the help.
